CU TTING APPARATUS FOR MOWERS OR REAPERS.

SPECIFICATION forming part of Letters Patent N 0. 691,461, dated January 21, 1902.

Application filed August 8, 1901. Serial No. 71,383. (No model.) I

To aZZ whom it may concern.-

Be it known that I, WILLIAM M. GOEHREND, a citizen of the United States, residing at Reed City, in the county of Osceola and State of Michigan, have invented certain new and useful Improvements in Cutting Apparatus for Mowers or Reapers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to cutting apparatus for mowers and reapers, and more particularly to means for compensating for wear of the joints of the movable parts of the cutting apparatus, whereby the finger-bar may be easily and quickly adjusted to maintain a true parallelism between it and the pitman, and-thereby prevent binding and breakage of the parts, which would inevitably result if the outer or divider end of the finger-bar sagged rearwardly.

WVith this and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, which will be hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a plan view of a fragment of the pole and a portion of the stationary frame of a mowing or reaping machine, illustrating'th'e application of my invention thereto. Fig. 2 is a vertical longitudinal sectional view through the shoe of the finger-bar and the parts thereto attached. Fig. 3 is a vertical transverse sectional view taken at right angles to Fig. 2 through the rear end of the shoe. Fig. 4 is a detail perspective view of the cap and plate. Fig. 5 is arear View of the finger-bar and coupling-bar to which it is hinged; and Fig. 6 is a rear view of the finger-bar shoe, illustrating a modification.

Referring to the drawings, 1 denotes a stationary part of the main frame of a mowing or reaping machine.

2 denotes the finger-bar; 3, the shoe; 4, the sickle-bar; 5, the drive-pitman, and 6 the coupling-bar. Projecting upwardly from the heel of the shoe are two'studs or posts 3 and 5", which are preferably cast integral with the shoe and are provided at their upper ends with screw-threaded shanks 7. Projecting upwardly from the shoe near its toe and arranged centrally on a line passed longitudinally through the center of the shoe and between the posts or studs 3 and 5 is a third post or stud 8. This stud or post 8 has a swiveled connection or adjustment with the shoe, so as to permit of the point of the shoe turning with respect to the stud, and this swiveled connection or adjustment may be effected by forming the stud or post with a shank a, which passes through a vertical aperture 9 in the shoe and has its extreme lower end screw-threaded to receive a nut 10, which is seated in a recess or countersink in the lower face of the shoe. The couplingbar has itsupper end pivolally connected to the stationary part of the mower or reaper frame and its lower end, which is preferably forked, connected by a pintle 11 to the swiveled stud 8 and pivotally connected by a pintle 12 to a box 13, mounted between the posts or studs 3 and 5 The width of this box is less than the space between the posts, and filling-blocks 14 are used for filling the spaces and preventing sidewise movement of v the shoe with respect to the box 13.

15 denotes a cap-plate which is placed over the upper ends of the posts or studs 3 and 5 with their shanks projecting above the same. Nuts 16 are engaged upon the shanks of the posts or studs 3 and 5 and tightly clamp the parts together.

In operation, assuming that the finger-bar is in a true line or is parallel with the drivepitman, when the filling-blocks are arranged between the stud or post 3 and the box 13 should there be wear between the hinged parts, so as to allow the outer end of the tinger-bar to swing rearward out of parallelism with the drive-pitman, the nuts 10 and 16 are loosened and the cap-plate elevated to permit of the withdrawal of one or more of the filling-blocks from its position between the stud 3 and box 13 and allow of its insertion between the box 13 and the stud 5*, thus adjusting the outer end of the sickle-bar forwardly or in true line with the pitman. After this has been done the nuts are clamped, thus securing the cap in position and the stud or post 8 fixedly to the toe of the shoe.

Another form of adjustment is shown in Fig. 6, inwhich it will be observed that I have dispensed with the filling-blocks and have substitutedin lieu thereof transverselydisposed set-screws 17, which Work through the studs or posts 3 and 5" and engage the opposite sides of the box 13. By tightening up one of these screws and loosening the other it will be seen that the same result is accomplished as is ascribed to the fillingblocksnamely, the shifting of the shoe to bring the finger-bar in parallelism with the drive-pitman.

From the foregoing description, taken in connection With the accompanying drawings, the construction, mode of operation, and advantages of my invention will be readily understood Without requiring a more extended explanation.

Various changes in the form, proportion, and details of construction may be made within the scope of the invention Without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is

1. In a cutting apparatus for mowers and reapers, the combination with the finger-bar shoe and the coupling-bar, of a post swiveled to the shoe and pivotally connected to the coupling-bar, a box slidably connected to the shoe and pivotally connected to the couplingbar, and means for adjusting the rear end of the shoe laterally with respect to the box, substantially as set forth. 7

2. In a cutting apparatus for mowers and reapers, the combination with the couplingbar and the finger-bar shoe,of a stud swiveled to the toe of the shoe and pivotally connected to the coupling-bar, studs, projecting upwardly from the heel ofthe shoe and spaced apart, a box connected to said shoe between said studs and pivotally connected to the coupling-bar, and means for adjusting the rear end of the shoe laterally with respect to the box, and a cap-plate secured to said studs, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.

WILLIAM M. GOEHREND.
